My most controversial pick would be The Amazing Colossal Man. The argument could be made for several other (better?) movies but TACM has always been a favorite since I was a kid. It’s hard to beat the nostalgia factor.

I was also glad to see Mysterious Island made the list. It’s not normally a movie listed for horror, but it did have some giant monsters so I won’t nit pick. Plus Mysterious Island is a fun movie.
